FIREPROOF SHUTTER.

To all whom it may concern:

Be it known that I, HUGH L. TURNER, a citizen of the United States, residing at Tampa, in the county of Hillsboro and State of Florida, have invented a new and useful Fireproof Shutter, of which the following is a specification.

This invention relates to fire-proof shutters and the like and its object is to provide a simple, durable, and efficient device of this character which is comparatively light and which will positively seal a window opening and prevent the admission of sparks, etc. thereto.

A further object is to provide a device of this character so constructed that the inner portions thereof will remain comparatively cool even though intense heat be directed against the outer portions thereof, the parts of the device being so assembled as to permit expansion and contraction due to the action of heat and cold from any cause.

Another object is to provide devices of this character containing air cells which are sealed so as to prevent the admission of foreign substances thereto.

A further object is to provide a shutter or similar device with means whereby it can be adjusted to fit stationary hinge members located at different distances apart.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a front elevation of two shutters embodying the present improvements, the same being shown closed. Fig. 2 is an elevation of the hinge end of one of the shutters. Fig. 3 is a section on line A-B, Fig. 1. Fig. 4 is an enlarged horizontal section through the hinge end of one of the shutters. Fig. 5 is an enlarged horizontal section through the meeting ortions of the two shutters. Fig. 6 is an en arged sec tion online CD, Fig. 1. Fig. 7 is a plan view of the hinge end of one of the shutters. Fig. 8 is a side elevation of the adjoining ends of one of the Tirons and the reinforcing strip of one of the shutters, said irons and strip being separated.

Referring to the figures by characters of reference, 1 and 2 designate upper and lower Specification of Letters Patent.

irons oppositely arranged so that the webs 3 thereof extend toward each other and interposed between these T-irons and at opposite sides of their webs are corrugated metal plates of steel or other suitable material, said plates being indicated at 4 and 5 and the innermost portions of their corrugations bearing upon opposite faces of the webs 3 and riveted thereto as indicated at 6. The two plates 4 and 5 do not extend be'yondthe side edges of the T-irons but have their outermost portions flush therewith and the plates extend across the ends of the shutter and are folded to form flanges 7 and 8. Each shutter has its flange 7 extending from the hinge end thereof and flush with its outer face while the flanges 8 extend from the meeting edges of the shutters, and are so disposed that the flange of one of th shutters will lap the outer face of the adjoining shutter while the flange of the other shutter will lap the inner face of the first mentioned shutter. This arrangement has been clearly indicated in Figs. 3 and 5.

Extending through the outer plate 4 of each shutter and close to the flange 7 thereof are hinge straps 9 extending beyond the flange 7 and inwardly between the plates 4' and 5, said straps being disposed in vertical alinement with the webs 3 and extending throughout the width of the shutter, the terminals of the straps being split longitudinally and being in opposite directions as shown at 10. These ends are bolted or otherwise secured to a reinforcing strip 10 extending-between the T-irons and having its terminals inturned and bolted or otherwise fastened to them as shown in Fig. 8. The plates 4 and 5 are secured -upon opposite faces of the straps 9 by means of rivets or in any other manner. It will thus be seen that these straps as well as the webs 3 hold the two plates 4 and 5 out of contact throughout their lengths and air cells are produced between the webs and the hinge straps. These cells constitute dead air spaces and when the outer plate 4 is subjected to heat the air confined within the cells will serve to insulate the inner plate 5 and protect it from the heat. The lower hinge straps 9 have eyes 12 at their outer ends designed to engage fixed pintles 13 extending from the wall or other supporting structure 14 to which the shut ters are connected. The projecting end of each upper hinge strap 9 is detachably conjustably mounted in this manner the 0 era tion of hanging the. shutter is greatly acilitated.

It will be seen that when the shutters are closed the flanges 7 thereof will lap the outer faces of the Window jambs while the inner flanges 8 will lap as indicated in Figs. 3 and 5 so that. the window opening will thus be tightly sealed against the admission of sparks, etc.

It will be seen that a shutter such as herein described can be readily manufactured at com aratively slight cost and-because of the nove arrangement of flanges and spaced air cells the. same is rendered very efficient.

Importance is attached to the use of the T-irons as. they not only constitute efficient posed corrugated plates, and oppositely exmeans for closing the ends of the corrugations and spacing the plates a art butthey also operate to reinforce the s utters in the direction of their widths.

Although the structure herein described is designed for use in connection with fireproof shutters it is to be understood that the same construction may be followed in the manufacture of fireproof doors and partitions. Inasmuch as no solder is employed in the construction of the device there is. little danger of any parts becoming separated as a result of the action of heat and moreover, said parts are free to expand and contract when subjected tov either heat or cold.

What is. claimed is:

1. The combination with spaced op ositely disposed T-ir0ns; of oppositely isposed corrugated plates interposed between the. irons. and secured upon opposite faces of the webs thereof.

i 2. The combination withoppositely disposed T-irons; of corrugated plates interposed between the irons and secured upon opposite. faces of the webs thereof, said plates forming air cellstherebetween, the irons con stituting closures for the ends of the cells.

3. The combination with oppositely dis posed corrugated plates forming air cells therebetween; of spacing means interposed between the end portions of the cells and constituting closures for said cells.

4. The combination with oppositely disposed corrugated plates; of hinge straps extending between and secured to the plates and constituting spacing devices.

5. The combination with oppositely dis- I posed corrugated plates; of hinge straps extending between and secured to the plates 1 and constituting spacing devices, each strap 3 having oppositely extending portions between the plates at one terminal thereof, and

a hinge member at its other end and beyond 1 the plates.

6. The combination with oppositely disposed corrugated plates and means extend-- I ing between and upon the plates for spacing ;them and closing the spaces therebetween; of hinge straps extending between and secured to the plates, said straps extending through one of the plates.

7. The combination with oppositely distending longitudinal flanges formed by the plates of spacing devices extending between and secured to the plates.

8/ The combination with oppositely disposed corrugated plates; of hinge straps extending therebetween ahd secured thereto, and a tubular hinge member adjustable longitudinally relatively thereto, and detachably connected to one of said straps.

9. The combination with oppositely disposed T-irons; of plates interposed between and secured upon opposite portions thereof,

reinforcing strips interposed between and secured to the irons, and hinge straps extending between the plates and having oppositely extending portions at one terminal thereof and secured to the reinforcing strip.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.

in the presence of two witnesses.
